Question

in how many years will Rs. 8000 amount to Rs. 9680 at 7% p.a. simple interest

Answer 1

Here,
SI=9680-8000
=1680
P=8000
R=7%
SI=P×R×N/100
1680 =8000×7%×N/100
1680÷7%=N×80
1680×100/7=N×80
24000=N×80
24000/80=N
300=N

Answer 2

P=8000
A=9680
R=7%
S.I.=A-P=9680-8000=1680
We kine that ,. T= S.I.×100÷P×R
T=1680×100÷8000×7
T=168/7=24
Hence time is 24 Month
Hance 2 year Time
